tgeogpointsegm_distance_turnpt() int tgeogpointsegm_distance_turnpt ( Datum  start1, Datum  end1, Datum  start2, Datum  end2, Datum param  UNUSED, TimestampTz  lower, TimestampTz  upper, TimestampTz *  t1, TimestampTz *  t2  ) Return 1 if the single timestamp at which the two temporal geography point segments are at the minimum distance. These are the turning points when computing the temporal distance Parameters [in] start1,end1 Values defining the first segment [in] start2,end2 Values defining the second segment [in] param Additional parameter [in] lower,upper Timestamps defining the segments [out] t1,t2 Precondition The segments are not both constants Postcondition As there is a single turning point, t2 is set to t1
